Be able to place the following events into their correct eon: Origin of the earth Origin of prokaryotes Increase in atmospheric oxygen Origin of eukaryotes Radiation of mammals Earliest human ancestors Origin of genus Homo

1) Select the concept below that best demonstrates compartmentalization of function in living things. Group of answer choices horizontal gene transfer flatness of flatworms organelles in eukaryotic cells circular chromosome of prokaryotic cells the Miller-Urey experiment gastrovascular cavity the RNA World hypothesis

Which of the following is NOT true about creationism? * no answer There is no extinction of organisms because organisms can always survive as long as they try hard enough. The earth was created only 6000 years ago because the evidence of the rocks suppor that idea. Any great change is due to small but cumulative changes that occur over long periods of time. All organisms are perfect because they are created to be able to survive in their habitat.

Imagine you are the head of a newly formed NASA Interplanetary Paleontology Department! Based on preliminary observations of a nearby planet (listed below), do you expect fossils to be in high or low abundance? Provide three evidence-based arguments to justify your choice, identifying the type of fossil record bias associated with each. Preliminary Observations: Volcanic eruptions and the formation of rift valleys and active subduction zones are regular occurrences on this planet. Algae and many soft-bodied animals are found in the oceans. A few leafy plants and a diversity of insect- and scorpion-like animals dominate the land at low densities. You can make the following assumptions: 1. The planet is of similar age and environmental conditions to Earth 2. Decomposition and other mechanisms relevant for fossilization occur on this planet as they do on Earth 3. Environmental conditions, species diversity, and population abundances in the past remained very similar to what is present now…

Please answer all

Please someone help me with Bio homework, thank you

Earth’s history is divided into unequal time intervals.  The boundaries between the intervals mark significant geological (very early Earth) or evolutionary events on Earth’s history.  Example: The boundary between the Precambrian eon and the Phanerozoic eon is marked by the rapid evolution and diversification of organisms with hard body parts.  The time intervals are eons, which are subdivided into eras.  The eras are subdivided into periods.  The periods are further subdivided into epochs (not shown on figure).   What is our current eon ______________, era _______________, and period _______________   Age boundary between the Hadean eon and Archean eon __________________   Age boundary between Archean eon and Proterozoic eon __________________   Age boundary between Proterozoic eon and Phanerozoic eon ________________   Age boundary between Paleozoic era and Mesozoic era ____________________   Age boundary between Mesozoic era and Cenozoic era ____________________   What…
